Abstract

This study aims to explore information related to the insight profile of elementary school teachers related to basic numeracy concepts based on learning according to the level where students are grouped according to their abilities. This study is a descriptive-qualitative study that describes the numerical insight profile of teachers from 6 elementary schools in Karang Sidemen Village, North Batukliang District, Central Lombok Regency, West Nusa Tenggara. The research activity was carried out in conjunction with the ‘Semua Anak CERDAS” training program for elementary school teachers in Karang Sidemen Village. The data collection process used numeracy test questions given to 30 research subjects. Each subject takes 1 topic which is discussed in depth regarding the concept of numeracy in learning based on students' abilities based on levels. Sub-aspects that become indicators of the teacher's numeracy insight profile include the components ‘Semua Anak CERDAS” approach, the scope of basic numeracy, grouping students based on basic numeracy skills, and the level of students' basic numeracy skills. The results showed that of the 30 teachers who took the numeracy test questions, only 6 teachers scored > 70. In addition, the schools studied with the lowest numeracy insight were SDN Rangkep and SDN Repok Sintung Barat.

Abstract

This research was conducted to analyze the difficulties experienced by high school students when solving problems regarding the line material. The method used is descriptive qualitative research. This research was conducted at one of the public high schools in Karawang for the 2020-2021 academic year with the subjects of class XII totaling 26 students. The technique for collecting research data is by giving a test in the form of description questions, amounting to 6 questions with predetermined indicators. Data analysis was carried out, namely data reduction, data presentation and drawing conclusions. The results of the analysis show that (1) students with heterogeneous mathematical abilities still have difficulty understanding and solving problems regarding the sequence material; (2) the students' difficulties with the sequence material, namely the lack of understanding of the questions and formulas to be used; (3) the students' abilities in understanding a concept in the Line material still need to be explored or trained more deeply.

Abstract

This study aims to examine the errors of XI grade students of the State Vocational High School in the city of Cimahi in solving transformation geometry problems. This research was conducted at SMK Negeri 1 Cimahi and the samples were taken as much as 1 class. The number of subjects in this study were 32 students. The research approach used is qualitative with descriptive methods. The data collection technique used was a test instrument. The test instrument used in this research is the National Examination (UN) questions on the transformation geometry material as many as 8 questions that have been validated. The results showed that the XI grade students of State Vocational High School in Cimahi City had errors in solving  transformation geometry problems. Problem number 2 is the most difficult problem with the question indicator calculating the image if it is rotated 270 ° with the center p (a, b), the average percentage is 3%, which means that only 1 out of 32 students answered correctly and many students had errors.

Abstract

This study aims to analyze and categorize in accordance with the validity, reliability and difficulty index of each item of barisan and series material in high school students class XII IPA 4 in one of the public schools in Cimahi city with a sample used by 28 people. The indicators used to analyze the problem are based on a revised Bloom Taxonomy that contains the cognitive domain levels C2 (understanding), C3 (Applying), C4 (Analyzing), C5 (Evaluating) and C6 (Creating). This type of research is qualitative descriptive research. The analysis is done by giving a written test in the form of a description question that amounts to 10 questions, then analyzing the test results that have been done. The method used is content analysis with the help of Microsoft Office Excel. The results of the analysis showed that out of the 10 question items tested there are 6 questions that can be used with the average result of validity and reliability in the moderate category as well as a difficulty index that shows the categories of easy, medium and difficult questions.

Abstract

Mathematics has an important role to play in life. But the reality in the field shows that many students still have difficulty in understanding math lessons, including geometry. The evidence in the field shows that the results of learning geometry are still low. The difficulty in understanding this geometry material has an impact on other materials related to the geometry material itself. Students will have difficulty in associating material with each other. This study aims to analyze the causes of students' difficulty in understanding Quadrilateral and Triangular materials in online learning. The research method used is qualitative method with case study type. The research subjects were taken as many as 9 students from grade VII E MTs Negeri 3 Purwakarta. The results showed that there are still many students who have difficulty in triangular and quadrilateral materials in grade VII MTs Negeri 3 Purwakarta caused by several different factors.

Abstract

This research was conducted with the aim of analyzing the difficulties experienced by students in working on BRSD material problems. This is taken from the cognitive indicators on the bloom taxonomy which are indicators of its difficulty. This research uses a qualitative descriptive method. The data collection technique is by giving questions to students. Furthermore, students' answers are analyzed to determine the extent of the difficulties that occur to students based on the determined indicators. This research was conducted at one of the state junior high schools in Cimahi for the 2020-2021 academic year. The subjects were 20 grade IX students. The instrument inside is a test item with predetermined indicators. The results of the analysis obtained are that there are still students who have difficulty solving indicators of problems that involve cubes. The above is evidenced by the results of the test questions to students where 70% of students experience difficulties with the question indicators as well as the percentage of student answers that are less than the predetermined KKM. The factors that make this indicator experience difficulties are (1) the students' lack of thoroughness in reading, understanding and answering questions; (2) Lack of students' spatial ability to imagine BRSD; (3) Students are accustomed to solving routine problems found in examples.

Abstract

Lack of information regarding mathematical knowledge obtained by students can result in these students experiencing epistemological obstacles. Meanwhile, the mathematical resilience possessed by students can help students get more information about mathematical knowledge that they have not completely obtained. This research methodology is included in descriptive qualitative research where the data collection technique is by using the Pythagorean theorem test method, mathematical resilience questionnaire and interviews. There were 23 respondents in this study who were students of class VIII 280 Senior High School. In this study the data were analyzed by identifying the answers of 23 respondents to the indicators of epistemological barriers and the mathematical resilience questionnaire that had been done by the students, then interviewing 6 respondents. The results of this study are that there are three types of students' epistemological obstacles in proving the Pythagorean theorem.

Abstract

This research intends to examine the student's misconception in completing comparative story problems. This research uses descriptive qualitative research methods, and the results will be analyzed to define the student’s level of capability on comparison materials. The research provides a test instrument with five problems of comparative story problems created based on bloom’s cognitive domain, with details 1 of the cognitive domain C2, C3, C5, and 2 questions of C6. The subjects in this research were 23 students of class 8 at one of the state junior high schools in Cimahi. Data analysis in this research is data reduction, data display, and verification. The results indicate that there was 1 student with high capability, 1 student with medium capability and, 21 students with low capability, the mistake made, including conceptual errors, principle errors, and algorithm errors, while the average class acquiring was 36.11%. Based on this, the conclusion is the student's capability to solve comparative material problems is still low so that increased capability is required.
